Fig. 4.
Two-dimensional histograms of, from top to bottom panels, the CR energy density, the Alfvénic Mach number 
, the ratio 
, and ζ = PCR∕P as a function of the density for the fiducial runs kturb = 2 with CR diffusion at the same time as in Fig. 3. The colour coding indicates the temperature, the magnetic field strength, and the sonic Mach number 
(two bottom rows), respectively.
